Coach Jim Harbaugh surprisngly pulled back the black curtains next to the locker room and showed off the 49ers’ bulletin-board material Wednesday.

“Show class, have pride and display character. If you do, winning will take care of itself.” — Paul “Bear” Bryant

“We win as a team. The Team. The Team. The team.”

“There is a right way. There is a wrong way. There is a better way. The FORTY-NINER way.”

“Who’s got it better than us? NOBODY!”

Defensive lineman Isaac Sopoaga wrote those quotes up on the white ink board, fulfilling his turn in what’s become a daily duty among players. Next to the board is a daily schedule with a corresponding player’s name, picked by wide receiver Michael Crabtree, Harbaugh said.

Harbaugh was so inspired by Sopoaga’s lede quote from Bryant that he charged into the locker room and proclaimed it his favorite thus far on the board.

“Everybody’s had a good quote,” Harbaugh said. “We’re documenting them. We take a picture of the guy next to the quote every day. Maybe there’ll be a coffee-table book some day.”

Although Harbaugh had team members take turns speaking up with “wise words” last season, the ink-board quotes have become a daily ritual carried out every morning and will continue all season.

Harbaugh often has recited motivational quotes from the likes of Bryant, former Michigan coach Bo Schembechler or war heroes, including his personal favorite, Winston Churchill.

As Harbaugh showed off Wednesday’s board, he looked at the other quotes and said: “There should be a footnote there.” Not just one footnote, either. Schembechler deserved credit for “The Team” mantra. Harbaugh penned the “Forty-Niner Way” mantra in a letter to season-ticket holders. And Jack Harbaugh first offered the now-famous “Who’s got it better than us?” catchphrase.

Has a player ever posted an opponent’s trash talk on that ink board? “That’s not the purpose of it,” said Harbaugh, who noted that such quotes are not necessarily forbidden as the board’s material is up to each player.

Sopoaga was ushered by Harbaugh to a pack of reporters in the locker room to not only explain Wednesday’s quotes — Sopoaga said he went on the internet and simply searched for phrases about “wants to win”– but to display the copious notes he takes daily in meetings.

Harbaugh opened up one of Sopoaga’s notebooks to show the detail and artistic efforts regarding the 49ers’ play calls and schemes. (Sorry, opponents, no pictures were taken.)

“Look at the detail,” Harbaugh marveled. “Nobody in the history of football takes notes like that.”

Sopoaga, a nine-year veteran and the 49ers’ second-longest tenured player, said he prefers writing in only black ink on the white paper, and he’s been taking eight to nine pages of notes daily since 2007. He attributed his penchant for such detail to his seven uncles who are ministers and how they prepared for their Sunday sermons.
